. In how many ways a relation can be represented? State two different

examples to represent each of them.

Answer 1

Relations can be displayed as a table, a mapping or a graph. In a table the x-values and y-values are listed in separate columns. Each row represents an ordered pair: Displaying a relation as a table

A mapping shows the domain and range as separate clusters of values. Lines are drawn to match each value in the domain with its corresponding value in the range:

Graphs can also be used to show the relationships between values. Each ordered pair is plotted as a point on the graph. The placement of a point along the x- and y-axes indicate the x- and y-values for the ordered pair:
